Blizzard gave Tailoring a lot of love in the Burning Crusades expansion. Tailors can make epic cloth gear that rivals gear dropped from raids.
Cloth wearers will find this a great profession to take up. Especially if you don't have time to commit to raiding.
Shopping List
You're going to need around 3000 gold for this level-up. You'll gain a lot of that back through the Auction House, vendoring, and disenchanting some of your items you make.
